Since this is getting some traction, I'll append with two additional thoughts:
I actually *do* think news orgs should spin up an instance for themselves, because [email protected] looks goofy, but reporters should set up where they want.
And "where they want" shouldn't probably all be on the same server bc that becomes a real tempting honeypot for defederation battles.
@dansinker I've been suggesting to my company to do the same. I mean, we've already got a .cloud domain, why not a .social one? Then we can FINALLY ABANDON THE HALF DOZEN TERRIBLE SOLUTIONS WE'VE TRIED SO FAR.
"Updates from your company!" are the worst e-mails I receive. at least Mastodon lets me filter by content language. (We're a very French org.)
Link-based verification is "okay" (for those technically inclined to check it), but alice@<company>.social is rather harder to spoof!
